Xa kuthengwa izivalo zebhabhathane, sisoloko sisiva amazwi evalufa yebhabhathane ekhonkxiweyo kunye ne-pinless butterfly valve.Ngenxa yezizathu zetekhnoloji, ivalve yebhabhathane engenaphini idla ngokubiza ngaphezulu kunephinifa lebhabhathane, nto leyo eyenza ukuba abathengi abaninzi bacinge ukuba ingaba ivalve yebhabhathane engenaphini ibiza kakhulu kunevalve yebhabhathane engenaphini.Ingaba ivalve yebhabhathane yephini ingcono?Kuthekani ngokuthelekisa phakathi kwevalve yebhabhathane ephiniweyo kunye nevalve yebhabhathane engenaphina?
Ngokwenkangeleko, owona mahluko ubalulekileyo phakathi kwevalve yebhabhathane ephiniweyo kunye nevalve yebhabhathane engenaphini ngulo: ingaba kukho isikhonkwane esincanyiweyo esimiyo kwipleyiti yevalve.Umdibaniso phakathi kwepleyiti yevalve kunye nesiqu sevalve enephini yivalve yebhabhathane yephini, kwaye ngokuphendululekileyo yivalve yebhabhathane engenaphini.Kwiivalvu zebhabhathane ezikhonkxiweyo kunye ne-pinless butterfly valves, zineenzuzo zazo kunye nokungalunganga.
Imeko ethile yile ilandelayo:
Uthelekiso lwembonakalo - ivalve yebhabhathane ekhonjiweyo ineentloko ze-pin ezicacileyo kwinkangeleko, engeyiyo igudileyo kwaye intle njengevalve yebhabhathane engena-pinless, kodwa ayinayo impembelelo enkulu kwinkangeleko iyonke.
Ukuthelekiswa kwenkqubo - isakhiwo kunye nenkqubo yokucubungula i-valve ye-butterfly ye-pin iya kuba yinto elula, kodwa ukuba ukugcinwa kuyadingeka emva kokusetyenziswa kwexesha elide, kuya kuba nzima ngakumbi ukukhupha i-shaft kunye ne-valve plate.Akukho lula ukususa isiqu sevalve kuba izikhonkwane zidla ngokubethwa zifunjwe kwaye zicinezelwe ngamandla ngocinezelo.I-valve ye-butterfly ye-pinless iya kuba nzima kakhulu kwisakhiwo kunye neteknoloji ngenxa yeendlela ezahlukeneyo zokuhambisa i-torque, kodwa ukugcinwa kwexesha elizayo kunye nokuchithwa kulungeleka ngakumbi kwaye kukulungele ukugcinwa.
Ukuthelekisa ukuzinza - Iivalve zeButterfly ezinezikhonkwane zizinzile kunezo zingenazo izikhonkwane kuba zigxininiswe ngezikhonkwane.Isakhiwo esingenazikhonkwane sichaphazela ukuchaneka kwesenzo ngenxa yokugqoka i-mating surface ye-shaft kunye nesango emva kwesenzo sexesha elide.
Uthelekiso lokutywina - Okokugqibela, makhe sijonge uthelekiso lwesiphumo sokutywinwa.Kukho intetho ethi ekusetyenzisweni kwevalve yebhabhathane enephini, i-medium inokungena ukusuka kwindawo apho i-pin ibethelwe khona phakathi kwepleyiti yevalve kunye ne-valve stem.Ingozi efihliweyo ebangelwa yile nto kukuba i-pin i-corroded kwaye iphulwe emva kwexesha elide, okubangelwa ukuba i-valve ingasebenzi, okanye ingxaki yokuvuza kwe-ejector okanye ukuvuza kwangaphakathi kwipayipi.
Ukushwankathela, ukuthelekisa i-valve yebhabhathane ekhonjiweyo kunye ne-pinless butterfly valve, ukuthetha ngokuthe ngqo, uyilo ngalunye luneempawu kunye neenzuzo zalo, kwaye akunakwenzeka ukuthetha nje ukuba yintoni engcono.Ngethuba nje sikhetha imveliso efanelekileyo kakhulu kwibhajethi yethu yeendleko kunye neemeko zethu zokusebenza, yimveliso elungileyo kuthi.
